Specification of Letters Patent.

Patented ug. 6, 1918.

Application filed December 20, 1917. Serial No. 208,075.

To all whom it may concern:

Be it known that I, JAMns DRONSFIELD,

a subject of the King of Great Britain and- Ireland, residing at the Atlas IVorks, Oldham, in have invented new and useful Improvements in Machines for Stripping the Waste Yarn Left on Condenser-Bobbins, of which the following is a specification.

This invention relates to a machine for stripping or removing the residuum waste condenser yarn left on condenser bobbins,

which bobbins as is known are of "consider-j able size. Such bobbins usually consist of a wooden'body with metal ends.

The attached drawings sufficiently illus-'- trate the construction of my condenser'bob I bin stripping machine.

In the said drawings I Figure 1 shows a rear elevation with certain of the parts in section and with the supports, &c., broken. away.

Fig. 2 is an end elevation.

Fig. 3 shows a section. I

Fig. 4 is an enlarged sectional elevation of the gearing end of the machine, while,

Fig. 5 shows a further sectional elevation taken at right-angles and on the line AB, Fig. 4. I I

In my bobbin stripping machine I use end standards a, a, or other suitable supports, which carry a trough shaped bed '6 adapted to receive alongitudinally arranged table or condenser bobbin rest 0' of suitable kind;

The bobbin table or rest 0 .illustrated'is of cast metal and has an inclined top 0" sloping downward from the back to the front edge 0 and with trued ledges c at each end. Such table 0 is adjustably or otherwise secured and ready means may be provided for ease in setting-up. Working in connection with such table 0 I employ a stripper device which takes the form of a cylinder at mount ed on the shaft (l and covered with card wire, teeth, or such like, the same being sup' ported in bearings such as bearings (Z (Z and driven in any appropriate fashion either direct or through gearing.

v The condenser bobbin 0 to be cleared is placed on the inclined top of the table 0 and so rolls or can be rolled toward the stripper device, the'flanges on the bobbin due to the planed ledges 0 c 'hold'ing the same against end movement while the stripper device does its work.

In order to keep the cylinder d or stripthe county of Lancaster, England,

' plate 7L the shaft 72, by akey h.

, per device effective for the object in view,

it is necessary to comb the stripper device as same rotates and this I do bya rotary comb combination which forms part of the machine and which I prefer to mount below thestripper device. The rotary comb combination consists of a slotted shell or tube 5/ the end supports of which are mounted in one set of bearings g g, and, of a shaft h which passes longitudinally through said slotted shell or tube gand is supported from another set of bearings h. k, such shaft 71, having an applied comb or a line of spikes or comb teeth k capableof emerging from and receding through the slot in the shell or tube 9. The bearings g g, h h, for the slotted shell or tube and the shaft with the comb teeth do not coincide, that is, the axial or center linesare not the same (see Figs. 1 and 4). I drive the slotted shell or tube 9 from the shaft 71. carrying the comb teeth, and this may be done by an accommodating coupling device as for instance abut ting flanges or plates [L g mayserve as the driving connection, the flange or plate '9 carrying a die 9 centered at g and which die engages a slot l1. in the other flange or The flange or plate k is fixed on Such a construction insures that the slotted shell or tube 9 and the shaft h with comb teeth 7& revolve at the same speed, but, during rotation, the teeth. I are advanced and withdrawn through the slot in the shell or tube 9 thus enabling the slotted sleeve 9 to strip the fiber from the comb :teeth. may be provided and the accommodating inter-connecting device may be variedand the comb performs its function a number of times for each revolution of the strippingcylinder or device d and thus effectively strips or clears the latter.

I may considerably vary the driving arrangement, but, at present, I drive the comb shaft it direct through a fast belt pulley z and'the: slotted sleeve'or tube 9 in unison, through the coupling device before described. j I

Uponthe comb shaft his mounted a worm j secured by a key y" and this "Worm ,j actuates a worm wheel is on a short upright shaft Z which carries a worm m gearing with a More than one set of teeth worm Wheel '12 on the shaft d of the stripping roller or cylinder (Z. The entire \vorm gears are inclosed in a detachable casing 0 as shown which is made in one or more parts and is secured by fixed studs and nuts 0"0. The loose pulley in the fast and loose pulley group is marked 2', and, the sliding bar 9 is the strap shifting device.

A detachable or othenprotecting canopy 7) is fitted in connect-ion with the stripping cylinder (Z.

The machine is easy to manage and simple in operation.

The bobbins to be stripped are placed 111 turn on the inclined table 0, and the woundon fiber comes under the action of the card teeth on the stripping cylinder cl which rapidly strip off the fibrous material, the stripping cylinder being quickly and continuously combed and the droppings deposited on the floor or dropped into a receptacle.

The machine can be run at a high speed because the comb shaft and slotted sleeve are well balanced and each runs on its own bearings.

So far as I am aware it is new to provide amachine to strip condenser bobbins and therefore I do not wish to limit myself with regard to any particular combination for the end in view so long as the result is achieved on lines substantially similar to what I have outlined above.

I declare that What I claim is.

1. A machine for stripping Waste yarn from flanged condenser bobbins having in combination an inclined bobbin support, flange engaging edges thereon, a rotating toothed cylinder, a comb shaft With teeth, a slotted tube around said comb shaft, an axle support for said slotted tube, bearings for the comb shaft, noncoinciding and independent bearings for the axis of the slotted tube, and an accommodating coupling de vice for the comb shaft and the slotted tube permitting the one to be dri en from the other and gear wheels to drive the toothed cylinder as set forth.

2. A machine for stripping \vaste yarn from flanged condenser bobbins, having a bobbin feeding table, edges on said table against which the flanges of the bobbins can bear, a rotating toothed cylinder, supporting means for said cylinder, driving gear therefor, a canopy for said cylinder, a rotating comb device,'a slotted tube surrounding said rotating comb device and adapted to clean the rotating comb device, independent bearings for the rotating comb device and the slotted tube and an accommodating couaccon'nnoda-ting coupling device interconnecting the comb shaft and slotted tube and gear -Wl1G8lS for driving the rotating parts as set forth.

4:. A machine for stripping \vaste yarn from flanged condenser bobbins, cou'iprising an inclined bobbin feeding table, ledges thereon for cooperating with the flanges of the bobbins, an independent rotating toothed cylinder in juxtaposition to such table, bearings in the machine therefor, a canopy for said rotating toothed cylinder clearing combination, comprising a comb shaft, teeth thereon, a slotted tube surrounding said comb shaft, bearings for the comb shaft, independent non-coinciding bearings for the slotted tube, an accommodating coupling device between comb shaft and slotted tube, all in combination and for the purpose described herein.

In testimony whereof I have signed my name to this specification.
